vice for breaking the electric current and producing the electric spark for the'purpose of igniting'the gas charge.

' The nature of my invention will be more readily understood by reference to the accompanying drawings and the letters referring thereto.

Fig. 2 is a longitudinal vertical section of the governor or regulator; Fig. 3, a longitudinal section showing the broken part of the cylinder and the gas-chest cut through the dotted lines a a, shown in Fig. 1. Figs. 4 and 5 are details.

The indicator 0 is designed to regulate the supply of gas.

The following is the construction of my improvement: I form the cylinder A similar in its general features to that of other gas-engines. I generally cast the igniting gas-chamber H and the receiving and mixing gas-chamber I with outer wall, B, and divided by partition 0. I connect the two chambers H and I through the valve G, which is upon the stem valve-rod N, to actuate the valve F by means of the tripper K, which is attached to the collar M upon the governor and gas-valve rod ernor is operated upon the sleeve-stem E, and

is held upon the same by the annular-groove connection Z. which allows it to revolve freely.

The operating parts are all connected with the' outer revolving sleeve, 0. The revolving pulley P is screwed to the end of the same. The lugs D are fixed parts of the same, and

the balls and levers N arejointed with the levers O,vhich are pivoted to the lugs and collar Q, which carry the connecting-hanger R, to which the stem F is attached by means of the nuts S. The pulley P is slotted, to allow the longitudinal motion of the stem F through the fixed sleeve E. The slot A allows the hanger R to move to the outer end of the fixed-stem sleeve E, which is suflicient to allow the required action of the governor upon the cutoff gear, allowing the tripping lever K to be thrown off of the lifting-block M on either side. in gear with the valve-stem gear L while it revolves concentrically with the stem F. The finger U is attached to the piston T and passes through the opening L at each backstroke of the piston, operating theleverV and breaking the contact of the points W and Y, and producing the electric spark, as is understood.

The following is the operation of my improvements in gas-engines: The piston T, being set in motion in the usual mode of starting gasengines, at the outward stroke sucks the valve G open, and the tripping-lever K, resting upon the1ifting-collar M", raises and opens the gas-valve F, admitting the required proportion of gas, which is regulated in quantity at will by operating the valve and indicator 0. The air is freely admitted through the pipe E, and as soon asthe full outward stroke of the piston is made and the cylinder filled with gas and airin proper proportions for combustion, and the valve closed by its own gravity, the piston is returned, compressing the gas, and the finger U, striking the lever V, pushes the same back, breaking the circuit at the points Y and W, and producing the spark and igniting the charge of gas and forcing out the piston T in the usual manner. I employ any of the well known methods for operating the exhaust of the cylinder after the full outward stroke has been cor ppleted. When the speed of the en- The annular toothed gear M remains f gine is greater than that designed, the gov: ernor-balls are thrown out and the stem F forced in, and the gear L and M partially IB-j volves the stem J and throws the tripping; lever K forward off of the lifting-collar M, and as it is again drawn out the valve G is sucked open; but the stem J is not lifted, and only air is drawn into the cylinder, and consequently no explosion is had in the cylinder until the speed of the governor is reduced and the spring S draws the stem F out, revolving the gear, so that the tripping-lever Kis again.

When the the lifting-collar M, thus cutting off the supply of'gas, as in the other case.

Having thus described my invention, what I claim, and desire to secure by Letters Pat- 1 ent, is, in gas-engines 1. The gas-valve F, with stem J, actuated by the gas and air valve G, with stem N, by

means of the lifting-collar M and the tripping-lever K, for the purpose of opening the gas-supply and admitting gas, constructed? and operated substantially as and for the purposes set forth.

'2. The gas-valve F, with stem J and segmental gear L, to operate in connection with any suitable governor, in combination with the gas and air valve G. stem N, and liftingcollar M", for the purpose of regulating the supply and cut-01f, constructed and operated substantially as and for thepurposes set forth.

3. The combination and arrangement of the setforth.
